HN ostensibly tries to have thoughtful, engaged conversations. LLM grammatical cleanups and translations are absolutely fair game. The comment has certain hallmarks (broad, sweeping summary, certain word choices, ...) suggesting that an LLM had more creative liberty than HN really likes to see -- in sort of an Uncanny Valley situation, it's hard to tell if the LLM produced the post or if a person did (plus, somebody apparently went digging and didn't see a lot of value in your other comments while also finding self-endorsements, which paints this one in a worse light).
You might have better luck with prompts that try to adhere better to your intent:
> English is not my first language. Please correct the spelling/grammar and perhaps teach me up to one idiom that would fit well in the following comment, but leave the meat of the message largely the same.
> Please translate the following [franglish/spanglish/(English mixed with a few words from your native language as appropriate to better convey your point)] to English suitable for a forum post.
